Description of the Invention (!) This application is a partial extension of the US Common Application No. 08 / 871,124, which was filed in 1997. It was applied for on June 9 and was transferred to the same assignee of the present invention. The co-application is hereby incorporated in its entirety for reference. The present invention relates generally to electronic devices of computers, and more particularly to an access structure β mounted on a computer case. For example, the electronic device case of a computer is usually made of a molded plastic material, and A device with an external opening for access by the user into the housing. An example of such a case opening is a slot opening pushed by a tower computer extending through a slot portion on the outside of the computer case structure. Such housing openings are typically provided with an access structure, which is usually also molded from plastic to selectively block and expose the opening. A common form of the access door is rotatably fixed to the housing recess by a hinge structure, for a pivoting action related to the following: (1) a closed position where the door stretches over and over Cover the opening of the body, and (2) an opening-restricted position pivoting outward, where the opening is not covered, and by the closeness of the inner edge portion of the door and the end face portion of the slot, the The door was restricted from further opening. There are many well-known problems, limitations, and disadvantages with this form of hinged plastic molded entry and exit. For example, many entrances and exits have exposed hinge structures, which will be damaged and unsightly. Other previously used access doors cannot rotate outward more than 90 degrees from the closed position, and therefore often block access to their associated slot openings. There is still a problem that will be combined with such conventional key entry and exit. If the entry and exit doors are strongly pivoted outwards and beyond their opening limit positions, this paper standard applies the Chinese Standard a (CNS) Α4 Specifications (210 × 297 mm) ------ ^ ------ Order ---, -----,-(Please read the notes on the back before filling this page) Intellectual Property Bureau of the Ministry of Economic Affairs Printed by the employee consumer cooperative 4427 20 A7 _______B7____ V. Description of the invention (2) ♦ The door and / or the associated recessed structure part will be damaged, and one or both of them need to be replaced " In a solution proposed by excessive pivoting, a pair of outwardly protruding arms are provided on a computer case entrance and exit door, and the hinge arms have a hinged structure that is rotatably coupled to the hinge structure on the general body slot structure. "Outer edge" Each cantilever is formed by two separable mating parts. When the door is turned outwards past its opening limit position, the arms are designed to be longitudinally separated from each other to allow the door And the inner cantilever part is separated from the outer cantilever part without being damaged, use the inner and outer parts Then the arm portion fitted function "allowable undamaged door groove is set back on the caulking groove. However, this design is quite complicated and costly, and does not provide a non-destructive separation action for this door. As can be easily found from the foregoing description, for a hinge structure with a concealment, there is more than 90 degrees full There is a need to open the doorway of the pivotally supported computer case without closing the fully open pivotal movement range and without damaging the disengagement and replacement performance. When implementing the principles of the present invention, according to its preferred embodiment, it is an electronic device, typically a tower CPU unit of a computer system, with a housing with an opening on the outer wall structure, with a thrust recess. The slot opening is used for illustration. * The electronic device also includes an access door, and the first and second mutually extending parts are respectively extended by the access door and the outer portion. The first and second intermeshing hinge portions define a part of the disengaged hinge structure that is noisy with each other, which can produce the following actions: (1) The door is supported to pivot the housing, that is, at the door.

Description of the invention ( 3) Rotate around the axis of the stick to make the access door and the shell opening cover and open each other, and (2) allow the access door to be dismantled from the housing interchangeably, in response to the access door being strong Pivot outwards beyond its opening limit position without damaging the door, hinge part, or housing. In order to achieve the removable disassembly of the door from the housing, the separate hinge structure also includes a decomposable structure, It is laterally offset from the hinge pivot, and should pivot outwards beyond its limit due to the access door, resulting in One of the first and second hinge portions generates an elastic cam force to release it from the other hinge portion. Preferably, the cam force elastically deflects one of the first and second hinge portions to be parallel According to other aspects of the present invention, the hinge structure is hidden when the access door is closed, and allows the access door to be supported as if it is between its closed and open limit positions, via a A turning arc greater than 90 degrees to increase the pivoting action of the door wall opening. In a preferred embodiment of the split hinge structure, the first key portion includes spaced first and second hinge arms. It has a body portion extending outward from the access door in the first direction and having a horizontal cut-out portion therein, so that the hinge structure is easy to hide and the access door has a body portion that pivots outward more than 90 degrees to its restricted position. A vertical ear piece is installed laterally on the outer edge of these body parts, and a round hole is provided on the outer end. Preferably, the access door and the two hinge arms are plastic molded. Two hinge parts include the first The hinge pin body and the second hinge part are spaced along the sacral axis. It is preferably spaced apart from the hinge chamber area of the shell wall structure, and the outer end is preferably a dome.

Description of the invention (4) The entry is effectively attached to the housing, and these hinge pins can be It is rotatably received in the earpiece space of the Qinjian J and the access door of the branch is pivoted relative to the cabinet between its closed and open restricted positions. The separation structure typically includes (1) a pair of separable pin bodies, each of which is placed in a spaced apart parallel relationship with a hinge pin, is laterally offset from the hinge pivot, and has a dome outer end, And (2) a beveled cam surface formed on each of the hinge arm vertical ears in response to the strong pivoting action that opens outward beyond the limit position of the access door to make the hinge arm ears parallel The frame shaft is skewed outside the combination with the hinge pins to separate the access door from the housing. By pressing the inclined, lead-in surface of the hinge arm adjacent to the hinge pin opening in the hinge pin opening adjacent to the hinge pin opening, the vertical ear piece is elastically deflected against the outer end of the hinge pin dome. The direction is usually parallel to the pivot axis' to allow the hinge pin to slide along the vertical ears and effectively snap back into the hinge pin holes.
